Four Channel Receiver with Matrix Decoding
Four channel finally comes of age with this versatile receiver from Pioneer, an outstanding achievement unusual in both capability and tremendous power output.
Featuring a unique matrix decoding circuit, that reproduces all regular matrix records, as well as a second type of decoding circuitry for the SQ matrixed type of records, the QX-9900 is simply the most complete receiver for four channel now available today.
In addition to it's matrix decoding capability, the QX-9900 may also be used for discrete four-channel reproduction as well as more conventional two-channel reproduction.
It's FM tuner characteristics are equally superb, distinguished by excellent sensitivity, a wide linear FM dial scale, and superb selectivity.
